Application filed May 9, 1906. Serial No. 315,886.

To .tZZ 1/;7'1/0771/ it may concern:

zen of the United States, residing at Hammond, in the county of Lake andState ol' In- .diana, have invented certain new and useful Improvementsin Reversible Fulcrums of whlch the following 1s a specification.

The invention relates to reversrbleiulorums for brake beams, andparticularly to mits of movement; to provide a fulcrum which may besecured to the trussed beam without having to slip the holding clip overthe end of the beam; to provide a fulcrum in -which the head of the kingpost constitutes the stop for governing its position rotatively; andfinally to provide an effective durable fulcrum of comparativelyinexpensive con- These and other objects are acdrawings in which Figure1 is a plan view showing the trussed brake beam with the fulcrumthereon;

Figure 2 is a perspective view of the fulcrum;

Figure 3 is a longitudinal section through the fulcrum shown in Figure2, on the line TIL-III;

Figure 4 is a transverse section through the fulcrum on the line IV-IVof Figure 3; and

Figure 5 is a transverse. section. through the fulcrum of Figure 2 onthe line V-V.

As shown in the drawings A is thebrake beam which may be of anypreferred design but is preferably a U shaped commercial section asindicated by the cross section in Figure 3,13 is the truss for the beamwhich in the present instance is round but which may. be of any desiredcross section, and C 1s the fulcrum which isdesigned to berotatablysupported on the brakebeam and truss whereby it may be used eitherlefthanded or right handed. The central portion of the revoluble kingpost 6 split intermediate its ends as in the ordinary type of fulcrums,and is provided with the hole 7 for the'pivot bolt. Be it known that I,CARL E. BAUER, a citlsecured to the .will be seen that this constitutesa very sim- The up er and of the king post 6 is brake beam A by means ofthe open sided clip 8 which clip as indicated in Figures 2 and 3,encircles the'beam and is secured by the throu h holding means or bolts9. The lower inside edges of the clip 8 are provided withprojectingportions l0 which portions are adapted to support the bushing11. The bushing 11 is divided centrally'as indicated in Figure 4 andforms a supporting memberfor the head 12 of the king post, therebysupporting it revolubly. The bushing is held in osition by means of thethroughbolts 9 which also secure the clip-8 in place. It will be seenthat by-using an open sided clip I am enabled to apply the fulcrum tothe beam without slipping the cli over the end of the beam, as such clipcan e laced over the top ofthe beam, and the bus ling 11 engaging thehead of the king bolt slipped in endwise and all secured together bymeans. of the bolts 9. It will be seen that the parts are very easilyassembled and when posit-ioned a very secure fastenin is provided forthe upper end of the king olt. As the device is designed to bereversible and the kingbolt must occupy positions at an angle of aboutto each other, such boltis mounted revolubly: at top and bottom and inorder to positively position the king bolt in either ,of these twopositions I construct my head in such a way that it will stop therotation of the kingbolt when it has arrived at either one of these twopositions This construction is.clearly shown in Figure 4, in which itwill be seen that the head 12 is in effect a pointed oval, and that inthe position shown in Figure 4 the points of the oval take against thesidesof the beam A and positively position the king bolt. that a motionof about 80 in a clock-wise direction will bring the pointsin engagementwith other portions of the beam thereby giv ing' the reverse position ofthe fulcrum. It

le andefilcient means for positioning the ring bolt and that no extra oradditional stops need be provided for this purpose. Thelowerportion ofthe king bolt 6 is supported It will be seenin the member l3 whichmember is provided with an upstanding portion l4 engaging the centralpart of the king bolt while the bottom portion thereof is recessed toreceive the truss B as clearly indicated in Fi ure 3. The

supporting part 13 is prevents from rotation by reason of its engagementwith the truss B and is provided with a stop for assisting in thepositioning of the king bolt as indicated in Figure 5. This stopconsists of an 11' standing flange 14 on the member 13 whic flange isadapted to contact with the parts 15 on the lower end of the king bolt.These stops correspond in osition with the stops on t e upper end of t eking bolt and the king bolt is thuspositively positioned not only at thetop but also at the bottom. The member 13 is provided with the usualperforated lug 16 to afford'a seat for the bolt to which a safety chainis attached to support the brake beam.- It will be seen from theforegoing'that my construction is a very cheap and inexpensive-one andone that may be applied expeditiously to the beam without any necessity'of sli ping the holding clip over the end of the beam. It will be seenfurthermore that the king post is positively positioned both top andbottom in a simple yet very effective manner without the necessity ofsupplying additional stops and recesses.

It will be apparent that the invention is capable of considerablemodification without departing from the spirit thereof. The beam is notnecessarily U shaped and in fact might be some other shape orrectangular and if .desired the pointed oval head of the king post mighttake against the sides of the clip instead of the sides of vhe beam. Itwill alsobe apparent that the head of the king post might be of a shapeother than a pointed oval as other shapes might be used wherein theshape of the head was such that it would bestop ped against the sides ofthe U shaped member at the desired points. My inventioncompreh'endsthese and other modifications whichwill be apparent to those skilledint-he art, and are within the scope of the in vent-ion,

Having thus described my invention and illustrated its use,.what .Iclaim as new, and

desire to secure by Letters Patent, is the following 1. Incombinationwith a brake beam, a fulcrum comprising an open sided cljipadapted to fit over the beam and provi ed with projecting inner edges, aheaded king post adapted to fit such clip and securing means interposedbetween the said inner edges and the head of the king post.

2, In combination with a brake beam, a fulcrum comprising an open sidedcli adapt-- 'ed 'to fit over the beam and provic ed with projectinginner edges, a headed king post d ma'to revolubly fit such clip andsecuring means interposed between the said inner edges and the head ofthe; king post.

3. In combination with a brake beam, at fulcrum comprising an open sidedclip adapt ed to fit over the beam and provided with projecting inner"edges, a headed king post adapted to fit such clip, securing meansinterposed between the said inner edges and the head of the king post,and through holding means to secure the clip to the beam and hold thesaid securing means in place.

4. In'oombmation, a supporting means U shaped in section, a king postprovided with. a

head fitting the supporting means, which head is shaped to be partiallyrevoluble in the supporting means but to be positively stopped at acertain point, by the engagement of the head with the sides of thesupporting means,

and means for securing the head against 1011-" gitudinal movement in thesupporting means. 5. In combination, a supporting means U sha ed incross section, a king post provided diameter approximately fitting theinside width of the supporting means, and means for securing the head inthe supporting means against longitudinal movement.

7. In combination with a 1'1russed brake beam, an open sided clip forthe beam provided with inner projecting edges, a king post supportingmember having an open sided recess to engage the truss, a king postprovided with a head engaging the clip and i a bottom portion engagingthe supporting member, and holding means interposed be tween theprojecting edges of the clip and the head of the'king post.

8. In combination with a trussed brake beam, an open sided clip for thebeam )rovided with inner projecting edges, a king po'st supportingmember having an open sided recess to engage the truss, a king postprovided with a head rotatably engaging the clip and a bottom portionengaging the supporting member, and holding means interposed between theprojecting edges of the clip and the head of the king post.

9. In. combination, a brake beam U shaped in cross section, an opensided clip therefor, and a king post revolubly supported therein andprovided with a head having stops adapted to engage the sides of thebeam and.

limit the movement of revolution.
